OXYGEN LANCE FOR UNSTEADY BLOWING THROUGH Russian patent published in 1994 - IPC

Abstract RU 2025498 C1

FIELD: ferrous metallurgy. SUBSTANCE: resonant cavity of jet is located along central axis of the tip on inner face surface of the oxygen lance. The resonant cavity consists of cylindrical cap and oscillation transformer in the form of a splitter of cylindrical shape with cap internal diameter and its depth are correspondingly 0.5 - 0.9 and 0.8 - 1.2 as to diameter of nozzle critical cross section. Diameter and length of the splitter are correspondingly 0.2 - 0.4 and 0.9 - 1.2 of the same parameter. EFFECT: effective blowing through in unsteady conditions. 1 dwg, 1 tbl
